No salt water around here. I pulled the boat to the side. And when I get some time I will pull it out. I was reading some other threads in them. Could be pretty neat to go with one of the T roadster bodies I have.

GRAB IT!!! The 181" can use many V-8 parts(including head with minor machine work). These were used a lot in midget racecars in the '70s & '80s, as so many V-8 parts could make a lower-budget & competitive racer(most camgrinders did grinds for them & their little brother , the 153" motor!
Yes, it'll do fine in a Model A, especially with a T5 behind it(std bellhouseings fit)

I have had one in my '32 roadster for the last 30 years. Excellent choice for a car that you don't want to cut up when changing the engine. An early ford transmission will bolt right up using the adapter from an SBC to early Ford trans.

When I did mine (mid eighties) there was no intake or exhaust manifold that could be used in a car. I solved the problem by bolting on a head from a 153 inch passenger car. The head is not as good (5 ports versus 8 larger ports) but you can run the passenger car manifolds and it works. The manifolds from the current 181 cubic inch industrial engine might work (see your local Chevy dealer). Someone may be making manifolds and I just haven't stumbled across them. Other than that you will need to build some manifolds.

The only one you are likely to find is the one made by Mercruiser. I have only seen them on some of their engines and don't know when they were used. They came from the factory painted black. It is my understanding that they were developed to quiet the noise from the engine. The first photos are from my '32 roadster. There was been a second one made by Ansen to go with their aluminum 8 port cross flow head. I used to have one of these heads and a valve cover and side plate came with it. The one I had had been modified and I tried in the 1990's to find another one but was unable to find anything at that time. I doubt that it was marketed separate from the head but don't know. It would take a little work to get it to fit the stock head. These are the last photos. Sorry about the duplicate posts but I am unable to delete them and don't have the time to figure out how.

I talked to a guy I know that runs the NAPA store here. He said he knew a guy he could talk to about these. I have seen some of the black valve covers. I'm going to pull the motor this weekend. And will go through it an check it out.

Their catalog says 3.0 (181) but they sure look like they are for the 153 heads. There could be a 181 head that I am not familiar with. The head on the top is the 181 that I am familiar with. There is paper stuffed in the exhaust ports of the 181 to identify them in the photo.

They emailed me back about their manifolds. And said they would only fit the industrial engine. I think they call it the vortec 3000. Maybe a head can be bought. I know where I can find a 2.5 head. Might be easier to go that way.
